Application filed October 15, 1919. Serial No. 330,817.

ber of continuous webs fed to the platen in superposed relation withcarbon sheets interleaved therebetween, and is an improvement upon myprior application, Serial No. 316,981, filed August 12, 1919.

In said prior application, the webs, which may be parts of a fan-foldweb, are carried around the'under side of a revoluble platen, and up infront thereof, the typwriting being done upon the front of the platen;and, in order to straighten out the webs to permit the carbons to bedrawn back independently of the webs, a delivery guide or chute,extending upwardly and forwardly from the front of the platen, is swungforwardly, thus reducing the bend around the platen of the webs andcarbons which are led into the machine horizontally at the rear of theplaten. The forward swinging of the delivery guide or chute also effectsthe actuation of a device for releasing the feedrolls which cooperatewith the under side of the platen. Little or no obstruction is thenencountered in pulling back the carbon sheets as required. The guide orchute is provided with a knife to enable the tearing off of sections ofthe webs, and also with a gage for determining the length of thesections to be torn off. A, releasable latch isprovided' formaintainingthe guide or chute in its normal position.

An object ofthe present invention is to provide novel means to enable a.condensed record-sheet, in the nature of a carbon copy, to be kept. Tothis end, there ma-yab employed a paper-shelf inclining forwardly anddownwardly toward the bottom of the platen, to direct the record-sheetbetween the platen and superposed webs or plies; and. if desired, a rollmay be provided upon the top of the platen for feeding this record-sheetand also for holding it during the manipulation of the carbon and webplies. This roll or rolls may be carried upon an arm or arms, and may bereleased by means of a finger-piece; and an apron or guide may beprovided at the rear of the platen to. guide the record-sheet back tothe top of said rear paper-shelf.

Another object of my invention is to provide means whereby the platenand consequently-the record-sheet will be line-spaced when theupwardly-extending guide is swung forward to enable the webs other thanthe record-sheet tobe pulled forward. To this end, provision may be madeof a train of connections by which the usual linespacing slide of theUnderwood typewriting machine will be operated up0nswinging the guide orchute forwardly. This provision relieves the operator of the necessityof effecting a separate actuation of the linespace mechanism inconnection with the aduStment. of the webs and carbons and thesubsequent severing of the webs; and guards against the superposition onthe recordsheet of the first line of a new section on the last line ofthe previous section.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 isa sectional side view of part of an Underwood typewriting'machine, modified to show one form of my invention as applied thereto.

Fig. 2 is a fragmentary perspective view of a carriage, showing theparts in writing position. l

Fig. 3 is a fragmentary sectional side view of the carriage, showing theparts positioned for withdrawing the carbon sheets.

F 1g. 4 is a diagrammatic side view, showing the feed-rolls moved fromthe platen bv the usual feed-roll release handle. y

In the Underwood standard typewriting' not shown, causes type-bars 1 tobe swung upwardlyand rea-rwardly against the front of a platen- 2, whichis journaled by means of {an axle 53in a shift frame 4.; The shiftframe4 is supported in the carriage 5 partly by means of arms-6 connected byshaft 7.

The carriage 5 is, supported upon a front rail, not shown, and a rearrail 8, which advantageously is located considerably lower than in theordinary Underwood standard typewriting machine, so that webs 9, drawnover a rear paper table 10, will be guided carbon-paper carrier orcarriage 14, which resembles in many of its details the usual Underwoodfan-fold carbon-carriage. The carriage 14 is shown as running upon rails15, which form arearward extension of the typewriter carriage, saidextension being supported at its rear end by a wheel 16 running upon arail 17 forming part of a fixed extension 18 of the typewriter frame.

In order to guide the webs 9 to the carboncarriage 14, they may be drawnover a rear bar 19 of the carriage provided with any* usual or suitableform of edge gage, not shown. 'hen the webs are introduced into themachine, they pass over the aforesaid paper-table 10 to the rearfeed-roll 11, and are then guided upwardly by an apron 20 supported onthe platen frame in any desired manner, so that the webs pass betweenthe front feed-rolls 21 and the platen 2, and then up in front of theplaten to a swing I uide or chute comprising a paper-table 22.

lhe apron 20 may extend well up toward the printing line.

The swing paper-table 22 is herein shown as provided with brackets 23 atits ends, said brackets being journaled by hubs 24 upon the platenaxle-3, to permit the swing, table to be swung forward from a stop 25fast upon an end frame 26 of the platen frame, against which it normallyrests, to the Fig. 3 position, at which it'is arrested by engagement ofa. tail 27 thereon With said stop 25. When the table 22. is swung forward to its Fig. 3 position, the angle through which the webs 9 and thecarbons 12 between them are turned is only about 60, and it has beenfound that this arc of contact on the ordinary Underwood standard platenis sufficiently small to allow the carbons to slip over the webssufficiently readily for the purpose in hand. When the paper-table 22 isin the F ig, 3 position, the operator draws the leading ends of the websto be gaged against a suitable adjustable end gage 28 fast upon anupward extension 29 of the table 22, and then, while holding the webs ingaged position, pushes the carbon-paper carriage 14 rearward by means ofits forwardly-extending handle 30.

Provision maybe made of an adjustable stop 31, for arresting thecarbon-can'iage 14 when the carbons 12 have reached any suitable pointbelow the severing knife 32, which is fast to the table 22, and standsin front of it, so that the webs and the carbon sheets are passedbetween the knife and the table.

When the leading edges of the carbons have been brought below thecutting edge of the knife 32, Fig. 3, the operator may swing the table22 rearwardly to its Fig. 1 position, so that it will be caught in saidposition by means of a hook 33, which is adapted to catch over a pin 34upon one of the swinging brackets 23, and hold the table 22 in itsnormal position. The webs may then be severed by drawing them againstthe knife, the feed-rolls 11 and 21 being sufficient to hold thewebsfirmly during this operation. To enable the table 22 to be readilyreleased from the hook 33, provision is made of ahandle 35, forming abell-crank extension of the hook 33, and adapted to swing the samearound shaft 36, against the action of a spring 37 which normally holdsthe hook in effective position. A stop 38 holds the hook 33 in'positionto be cammed upwardly by the pin 34, when the table 22 is swungbackwardly.

In order to relieve the operator of the need of separately casting offthe feed-rolls 11 and 21, and to insure actuation of the parts in properorder, the swinging bracket 23. may be connected by a link 39 to arockarm 40,, fast upon the usual feed-roll-casting-off shaft 41 of theUnderwood platenframe, the connections being such that when the hook 33holds the table 22 rearwardly, the feed-rolls are effective, but, whenthe swing-table is in the Fig. 3 position, the feed rolls areautomatically released.

In order toassist in guiding the webs 9 across the paper-table 10 to theplaten, pro vision may be made of a paper-guide or shield 42, which liesabove the paper-table 10, and is supported at each end by a bracket 43,secured to the typewriter carriage 5. I

The usual line-space-ratchet-wheel 44 is secured on the axle 3, and isactuated by means of the usual line-space-s'lide 45, operated, in turn,by a line-space-lever 46, the operative connection between theline-spaceslide and ratchet-wheel being effected by means of the usualpawl 47 The number of line-spaces through which the platen is moved ateach actuation of the line-space-lever 46, may be varied, for one, twoor three spaces by the usual line-spacecontrol handle 48.

The paper-table 10 is supported by means of abar 49, from whichextendposts 49, carrying bracket 50, which support the rails 15, said railsbeingconnected by rods 51. The mechanism, so far escribed, issubstantially the same as that disclosed in said prior application,Serial .No. 316,981.

In order to keep a record on a separate sheet or web 52, provision ismade of a paper-table 53, of substantially the-usual form.

The record-sheet, when placed in the machine, passes from saidpaper-table 53 around the platen, and beneath the lower edge of thepaper-table 22, being pressed against the upper part of the platen bymeans of an auxiliary feed-roller 54. Said roller 54 is supported upon ashaft 55, carried by arms 56, securedto shaft 36, a handle 57 being-'58, connecting a lug 59 on said handle 57 with a pin fixed in'theplaten-frame, the

handle 57 being arran ed near the righthand end of the platen-frame. Inorder to assist in guiding the forward end of the record-sheet 52 abovethe, top of paper-table 53, when inserted in the machine, a guide orshield 60 is secured to shaft 36, so that when the auxiliary. roller54-is withdrawn from thc platen, shield60 will-be in proper position toreceive and direct the forward end of. the record-sheet to the rear ofthe machine.

It will be noted that after the webs have been severed, at the end ofthe operation previously, described, fresh portions of the webs willhavebeen positioned at the print ing line, due to the initial drawingforward of the webs. The recordsheet, however, being pressed against theplaten 2, by the auxiliary feed-roller 54, would not be advanced withwebs 9, and consequently the line last written would still be at theprinting line. This condition may be corrected by manu ally line-spacingthe platen to advance the record-sheet. It is desirable, however, torelieve the operator of the necessity of erforming a separate operationof line-spacing the platen, in connection with the operation of theother parts, by providing means for effecting automatic line-spacing ofthe platen, when the paper-table 22 is swung forwardly. To this end,provision is made of a ted end 62 of a=lever 63, i the platen-frame, andhav ng, at its other end, a pin 65. engaging a slotted portion 66 of alever 67, pivoted at 68 on the platen- V frame, and having a nose 69 atthe end of a downwardly-extendlng portion thereof,

for engagement with the forwardend of the line-space slide 45. Forward,movement of bracket 23 will then effect, by means of the levers 63 and67 and the line-space-slide 45, a line-space movement of the platen toadvance the record-sheet. The other steps of advancing the webs 9 to theend gage 28, retracting the carbons 12, and severing 'the typewrittensections of the webs, will then be effected in the usual order, and uponreturn of pa'per-table 22 to normal position the webs, the record-sheetand the inter pin 61 on bracket 23, engaging a slotivoted at 64 onleavedcarbons will be in position to start work afresh, I

With this arrangement, itwill be seen that the record-sheet isautomatically linespaced through one, two or three line-spaces,

according to the setting of the line-space- Provision is made. to castoil or releasethe'feed-rolls by the usual finger-piece 74 (Fig. 4)pivoted at 75 on the right-hand end of the platen-frame 4, so that thefeed-rolls may be released independently of the swingframe. Thefinger-piece 74, when actuated. pulls upwardly on a link 76 connected toa crank-arm 77 on the right-hand side of the shaft 41 to: rock thelatter and release the feed rolls 11 and 21,- as hereinb'efo're described. It is desirable to maintain the feed-rolls .in their releasedposition when cast off by the finger-piece 74, so that both hands of theoperative may be free to properly adjust a work-sheet around the platen.For this purpose, the finger-piece 74 is effective to rock the shaft 41through a greater angular distance, than when actuated by theswing-frame, so that the return springs have no effect to restore thefeed-rolls.

To permit the releasing of the feed-rolls by the finger-piece 74independently of the swing-frame, the link 39 connected to the'swing-frame and the rockshaft 41 is provided with a slot 78.

Variations may be resorted to within the scope of the invention, andportions of the im rovements may be used without others.
